Not to be the ever-present contrarian, but I'm kinda noticing the opposite. Compared to the average Warriors game, the graphics and motion look far more appealing here than they usually do. Maybe I'm just biased in appreciating the relatively limited flash effects from Kasumi's attacks not obfuscating everything, but I can tell what's going on in all these clips, which is very rare for a Warriors game and most welcome.
So call me crazy, but I think some of you are mentally comparing the Kasumi footage to a Tecmo/Team Ninja game rather than a Koei game. And by that standard sure, it's sub-par. But compared to a Koei game? Doesn't look too bad, IMO.
